02 4Runner Millenium Edition Throughing Codes. Your help appreciated!
I have an 02 4Runner Milennium Edition that is throwing the following codes:
P0440 - EVAP Emission Control Sys: Malfunction
P0441 - EVAP Emission Control Sys: Incorrect Flow
P0446 - SAE - Evap System Vent Control Circuit Malfunction
I made sure my gas cap was tight and I checked the vacuum line connection next to the breather hose on the airbox. Everything looked good so I reset the codes. The c/e light was off the whole ride home and to work (about an hour total) when it came back on. Any common issues that may be causing this? Any diagnostic how to's I can follow?
Thx!

I have pressure release when I remove my gas cap (almost seems excessive) so I'd assume my gas cap seal is good. My idle rpm's (in drive) while at a stop are around 700... I haven't noticed any fumes gas or other.
